Leviticus 23:28-39

²⁸You must do no work on that day because it is the Day of Atonement, to make atonement for yourselves before Yahweh your God.

²⁹Whoever does not humble himself on that day must be cut off from his people.

³⁰Whoever does any work on that day, I, Yahweh, will destroy him from among his people.

³¹You must do no work of any kind on that day. This will be a permanent statute throughout your people's generations in all the places where you live.

³²This day must be to you a Sabbath of solemn rest, and you must humble yourselves the ninth day of the month at the evening. From evening to evening you are to observe your Sabbath.”

³³Yahweh spoke to Moses, saying,

³⁴“Speak to the people of Israel, saying, 'On the fifteenth day of the seventh month will be the Festival of Shelters for Yahweh. It will last seven days.

³⁵On the first day there must be a holy assembly. You must do no ordinary work.

³⁶For seven days you must offer a sacrifice made by fire to Yahweh. On the eighth day there must be a holy assembly, and you must make a sacrifice offered with fire to Yahweh. This is a solemn assembly, and you must not do any ordinary work.

³⁷These are the appointed festivals for Yahweh, which you must proclaim as holy assemblies to offer sacrifice by fire to Yahweh, a burnt offering and a grain offering, sacrifices and drink offerings, each on its own day.

³⁸These festivals will be in addition to the Sabbaths of Yahweh and your gifts, all your vows, and all your freewill offerings that you give to Yahweh.

³⁹Regarding the Festival of Shelters, on the fifteenth day of the seventh month, when you have gathered in the fruits of the land, you must keep this festival of Yahweh for seven days. The first day will be a solemn rest, and the eighth day will also be a solemn rest.
